Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
236 words
A photographic camera comprising a film magazine receiving chamber formed in the camera body on one side of the film aperture, which chamber has an opening open toward the bottom face of the camera body and shaped to permit insertion of a film magazine into the chamber only in one axial direction of the film magazine, film leader guiding means for guiding the leader of the magazine to extend in a proper direction when the magazine is inserted into the chamber, film leader cutting means disposed on the side of the film aperture opposite to the film magazine receiving chamber, and a back lid which can be opened through a limited opening angle to expose said opening of the film magazine receiving chamber, said back being mounted to swing about an axis extending along an upper transverse edge of the camera body; said cutting means comprising a cutting blade fixed on the camera body and a movable cutting blade movable with the back lid, the fixed and movable blades being positioned to cooperate with each other to cut the film leader when the back lid is closed, said movable cutting blade being swingably mounted on the camera body at one end, and connected to the back lid at the other end in a manner which limits the angle of the swinging movement of the movable cutting blade, thereby limiting the opening angle of the back lid.
